Please try the following methods to solve your problem: 1. If you are using USB devices (keyboard or mouse, for example) on your desktop PC, please plug in the device with the USB ports on the back of the PC, instead with the front ones. 2. Please use the device on a different computer to see if the problem happens on different computers as well. If the problem is solved on the other computer, then the problem has to do with your original computer itself. 3. If none of these method works, please contact us.
